 ## SIG group work objectives and scope
-- To solve the problems such as lack of functionality, low performance and high resource consumption existing in the current log system, we establish this sig to design a new log system HiLog for OpenHarmony. HiLog stores and manages various types of logs, including kernel logs, system logs and third-party logs. It provides rich and convenient log access functions for system developers and application developers. At the same time, HiLog has good performance in log reliability, interface delay and resource overhead.

 ## SIG组工作目标和范围
 
 ### 工作目标
-- 针对当前已有日志系统存在的功能缺失、性能较低、资源开销大等问题，成立本sig，目标是为OpenHarmony设计一个全新的日志系统HiLog，能够存储和管理内核日志、系统日志以及三方日志等各种类型的日志，为系统开发者和应用开发者提供丰富便捷的日志访问功能，同时在日志可靠性、接口时延、以及资源开销等方面具有良好的性能体验。
